Here, you can read a narrative essay on air pollution in English. You can also clearly know about the meaning, sources, effects, and control measures of air pollution.
Air pollution means some poisonous substances are include in the air and making it unpure for natural purpose. Nowadays, Air pollution as become one of the major problem that affects every creature on earth.
Air pollution can be defined alteration in physical, chemical, and biological characteristics of air making it unsuitable for designated use in its natural state.
Meaning of Air pollution:
Air pollution is a type of environmental pollution, which affects air. It is an atmospheric condition in which certain substances are present in concentrations which can cause undesirable effects on man and environment.
These substances include gases, particulate matter, radioactive substances etc.
- Gaseous pollutants include oxides of sulphur, oxides of nitrogen, carbon monoxide, hydrocarbons.
- Particulate pollutants include smoke, dust, soot, fumes, aerosols, liquid droplets, pollen grains, etc.
- Radioactive substances include radon-222, iodine-131, strontium-90, plutonium-239, etc.
Sources of Air pollution:
Air pollution occurs in two ways. The main of these is man-made pollution and the second is pollution caused by certain events in nature.
The natural sources of air pollution are volcanic eruptions, forest fires, sea salt sprays, biological decay, pollen grains on flowers, spores, etc. Radioactive minerals present in the earth’s crust are the sources of radioactivity in the atmosphere.
Man-made sources include thermal power plants, industrial units, vehicular emissions, fossil fuel burning, agricultural activities, etc…
Effects of air pollution:
It is difficult to describe in words how this air pollution has a profound effect on the health of all living things.
Effects on Human Health:-
Air pollution affects human health. Suspended particulates can cause damage to lung tissues and diseases like asthma, bronchitis, and cancer.
Effects on Plants:-
Air pollution affects plants by entering through stomata, destroy chlorophyll, and affects photosynthesis. Damage leaf structure causes necrosis, chlorosis or epinasty, and abscission.
Effects on aquatic life:-
Air pollutants accumulate together with rainwater in ponds and freshwater lakes and rivers. It has a profound effect on all living organisms in the water. This becomes very dangerous for their survival.
Effects on materials:-
Because of their corrosiveness, particulates can cause damage to exposed surfaces. SO2 can affect fabric, leather, paint, marble, paper, and limestone. Ozone in the atmosphere can cause cracking of rubber.
Controlling measures of air pollution:
Air pollution can be minimized by the following methods:
- Air pollution can be mitigated to some extent by setting up industries following proper environmental impact assessment studies.
- Using low sulfur coal in industries.
- Removing sulfur from coal.
- Removing NOx during the combustion process.
- Vehicular pollution can be checked by regular tune-up of an engine; replacement of more polluting old vehicles; installing catalytic converters.
- Using mass transport systems, bicycles, etc.
- Shifting of less polluting fuels.
- Using non-conventional sources of energy.
- Using biological filters and bio-scrubbers.
- People should consider it our responsibility to plant as many trees and protect the forests. The more trees we plant, the better it will be for our future generations.
Since we are aware of the effects of air pollution, the control measures outlined above should be followed to reduce air pollution and provide clean air to future generations.
